Sodicity and water quality effects on slaking of aggregates from semi-arid soils


, : Sodicity and water quality effects on slaking of aggregates from semi-arid soils. Soil Science 168(8): 552-562

Aggregate slaking is one of the main mechanisms responsible for the breakdown of aggregates. Exchangeable sodium percentage (ESP) and electrolyte concentration (C) of the soil solution play a significant role in determining soil physical properties and the response of soil clays to dispersion and swelling. However, studies of sodicity and C effects on aggregate stability have yielded inconsistent results.
